drm/exynos: fix interlace resolutions for exynos5420
Modified code for calculating hdmi IP register values from drm timing values. The modification is based on the inputs from hw team and specifically proposed for 1440x576i and 1440x480i. But same changes holds good for other interlaced resolutions also.
